How to fix “Insufficient Gas Fee” error?

Why am I getting an “Insufficient Gas Fee” error?

On Halo Wallet, a “Insufficient Gas Fee” pop-up window shows when you move or swap coins. This indicates that you do not have enough of the native token of your network in your account to pay for gas fee.

Gas fee is often needed for every transaction, including token and contract transactions. This can be compared to a transaction fee. The amount of computational work needed to handle transactions and smart contracts is measured in gas.

The term refers to the fluctuating, occasionally expensive cost of operating, similar to the petrol that fuels an automobile engine. Similar to how a bigger, more potent car uses more gas to run, more complicated smart contracts need more gas to power their calculations.

Some examples of native tokens are shown in above image.

• Ether (Ethereum mainnet, plus layer 2 networks such as Arbitrum or Optimism),

• BNB (for BNB Chain, formerly BSC)

• MATIC (Polygon),

• KCS (KCC),

• FTM (Fantom),

• AVAX (Avalanche C-chain).

What can I do to fix it?

This can be fixed by transferring some of the required native token to that account so that the transaction can be completed.

If you need to purchase native tokens to have enough funds to complete a transaction, you can either transfer the token from an exchange like KuCoin to your wallet or use the bridge feature on a decentralized exchange (DEX) to trade other tokens for the native token you want.
